ZONE MASTER with dap4 User’s Guide 

1.0 Introduction 

The Zone Master offers unit lead/lag, rotation and a teamwork control solution for Data Aire units. 

The Zone Master consists of one Master Unit and up to fi fteen (15) Slave Units. Unit #1 is always 

assigned as the Master Unit (U1). Units #2 through #16 are slave units. Zone Master control logic 

is confi gured in the Master unit. 

The Zone Master units are connected together in a daisy chain topology using the dap4 pLAN 

communication port (see the dap4 Zone Master wiring connections on page 9). 

Note: The Zone Master is optional and requires an Activation Code for each unit in the zone. 

The Zone Master provides selectable logic choices as listed below: 

4 

• Auto Lead/Lag Standby Rotation 

• Secondary Operating Schedule for Economical Control 

• Activate Standby Unit on Selectable Alarm 

• Turn Unit Off Selectable Alarm 

• Zone Inhibit Control Preventing Units from Confl icting Operations 

• Standby Unit Activation on Temperature Control 

1.1 Logic 

1.1.1 Auto Lead/Lag Standby Rotation and Temperature Assist Logic – provides a means to automatically 

rotate the designation of STANDBY among a group of units that must be ON based on 

programmable schedule. 

The user may assign a number of units to a zone where a number units must always be ON and 

others in STANDBY or OFF. ON units will have a PRIMARY designation on their status page at 

the Zone Master’s display screen. 

ON units will have a ONbyZM (On by Zone Master) designation at status display. 

STANDBY will have a STBbyZM (Standby by Zone Master) designation. 

Units that are ONbyZM but do not display the PRIMARY designation, have been brought ON by 

the Zone Master because of a temperature requirement or an alarm. 

OFF units will have a OFFbyZM (Off by Zone Master) designation. 

The OFF mode setting will cause the blower and all cooling, heating, dehumidifi cation and humidifi 

cation functions to be held off regardless of the zone’s requirements. The main control display 

will display the following message: OFFbyZM 

The message will also be displayed in the summary page of the master unit (such as – Status: 

OFFbyZM).

In the STDBY (standby) mode there are two scenarios: 

1. The unit that has been selected to always run (ONbyZM – Primary as shown in the master unit 

display) will operate non-stop providing all cooling, heating, dehumidifi cation and humidifi cation 

functions required. The blower will run continuously for ventilation and provide airfl ow across the 

sensors for accurate temperature and humidity requirements even if no cooling, heating, dehumidifi 

cation and humidifi cation are required. 

2. The standby units that are not required to always run will hold off the blower and all cooling, 

heating, dehumidifi cation and humidifi cation functions unless among the units which are ONbyZM 

the average return air temperature in the zone is more than the average setpoint plus average 

deadband plus 1.5°. If this occurs, one of the STBbyZM will change its status to ONbyZM. The 

blower of the standby unit will start and the standby unit will then be allowed to regulate cooling as 

if it was in the ON mode. Normal operation messages will be displayed whenever a standby unit 

has been reactivated for operation. 

If the temperature and humidity condition at the standby unit are satisfi ed, it will return to inactive 

(STBbyZM) when the average zone temperature is maintained below the average setpoint plus 

the average deadband for 15 minutes (this is adjustable and has a range from 30 to 999 seconds). 

If the temperature or humidity condition at the standby unit isn’t satisfi ed even though the zone’s 

average temperature is maintained below average setpoint plus deadband for 15 minutes (adjustable), 

the unit will continue to run until its temperature and humidity is satisfi ed. Its status will be 

RUNtoSTB (run to standby). Once its own temperature and humidity setpoint is reached, if the 

zone average temperature is below setpoint plus deadband, the zone master will turn the unit to 

standby and the status will be STBbyZM. 

Example - With four units assigned to a Zone, two units must be always ON and one unit always 

OFF, the settings are as follows: 

Zone Master 

Zone ID: 1 

Units in Zone: 4 

Units Online: 4 

Primary Schedule Only 

Number of Units On: 2 


Note: 

Unit #1: 

Unit #2 

Unit #3 

Unit #4 

U1 is the Master 

Stdby 

Stdby 

Stdby 

Off 

5

Based on the above settings, the zone logic will automatically set unit # 1 and unit # 2 as ONbyZM 

(On by Zone Master). Unit # 3 will be STBbyZM (Standby by Zone Master). Unit # 4 will be OFFbyZM 

(Off by Zone Master) 

Typical Screen (values for reference only): 


Note: U1 is the Master 

Unit #1: ONbyZM 

No Alarm 

Temperature: 73.5 o 

Humidity: 48% 

Primary 

Units that are set to OFF by the Zone Master do not rotate. Auto rotation start time can be set to 

OFF for no rotation or to any hour during the day for rotation. Rotation can be programmed to occur 

every 8, 12, 24 hours or day of the week. 

Assume 24 hours rotation, on the status page of each unit the following will be displayed: 

6 

Unit Number 1 Unit Number 2 Unit Number 3 Unit Number 4 

Day 1 ONbyZM ONbyZM STBbyZM Off 

Day 2 STBbyZM ONbyZM ONbyZM Off 

Day 3 ONbyZM STBbyZM ONbyZM Off 


Day 5 STBbyZM ONbyZM ONbyZM Off 

Day 6 ONbyZM STBbyZM ONbyZM Off 


Note: 

- If communication with the Zone Master is broken, all units will operate independently and 

for the fi rst fi ve (5) minutes, the message will displayed at on each unit’s display screen: 

“Master (U1) has Gone Offl ine” 

- If communication between a slave unit (for example Unit #3) and the Zone Master is broken, 

the Master will exclude Unit Number 3 from its calculation and report on its status loop: 

“Unit 3 is Offl ine” 

During this time, Unit Number 3 will operate independently on its own setpoints. 

The auto Lead/Lag Standby Rotation Logic is enabled through the Zone Master (see Programming 

and Selection section). 

One unit is designated the Master (U1). Each individual unit may be set to OFF or STDBY (Standby).

1.1.2 Standby Alarm Logic – Within a zone one or more units may be designated as STANDBY 

(STDBY) units which are only available when required by an alarm condition. The Zone Master is 

designed to detect alarm conditions and to activate standby units as necessary. 

Note: Standby unit activation and deactivation are independent of other zones 

The user may assign one or more alarms as “Standby Alarms” by selecting Y (yes) in Zone Master 

Alarms page (see Zone Master Set-Up). The Zone master temporarily activates standby units to 

supplement units that have experienced one or more Standby Alarms per the following rules: 

• For each unit in a zone that experiences a Standby Alarm, a standby unit will activated (if 

available) in that zone 

• Once activated, each activated standby unit remains ON until the Standby Alarm has gone 

away and for fi fteen minutes (adjustable) thereafter. 

1.1.3 Off Alarm Logic – Within each zone one or more units may be designated as Standby 

(STDBY) units which are only available when required by an alarm condition. The Zone Master is 

designed to detect alarm conditions and to activate standby units as necessary. 

Note: - Standby unit activation and deactivation are independent of other zones. 

- Off alarm and standby alarm selection can not be duplicated. 

The user may assign one or more alarms as “OFF” by selecting Y (yes) in Zone Master Alarms 

page (see programming and selections section). The Zone master temporarily activates standby 

units to supplement units that have experienced one or more OFF alarms per the following rules: 

• Whenever an ON unit is on by the Zone Master (OnbyZM) experiences an OFF Alarm, the 

Zone Master immediately reconfi gures the unit to OFF (OffbyZM). If there are any standby 

units available in the affected zone, the Zone Master reconfi gures the standby unit with the 

lowest identifi cation (ID) number ON and changes its status to ONbyZM (on by Zone Master). 

• Any reconfi guration accomplished by the Zone Master in response to Off Alarms continues 

until the user manually changes the status setting through the Zone Master’s menus. 

• The last ONbyZM unit in the zone will remain on even when an Off Alarm is detected. 

1.1.4 Zone Inhibit Control Logic – Logic stops units within the same zone from engaging in counterproductive 

heating and cooling or humidifi cation and dehumidifi cation at the same time in the 

same zone. Reheat is not considered in the Inhibit Logic since it only accompanies dehumidifi cation. 

The logic in enabled by selecting YES for the Inhibit Control in the Zone Master (see programming 

and selections section). 

7

The following rules apply: 

• Cooling/Heating 

o The Inhibit Logic can only be infl uenced by units that are within 3°F of the average measured 

zone temperature. This prevents a unit with mis-calibrated sensor from causing 

an inhibit function. Units set to OFF mode are not included in the average. 

o If any unit within the zone is currently cooling or starts cooling, then all other units within 

the zone are inhibited or prevented from continuing or starting heating. 

• Humidifi cation/Dehumidifi cation 

o The Inhibit Logic can only be infl uenced by units that are within 5% of the average measured 

zone humidity. This prevents a unit with mis-calibrated sensor from causing inhibit 

function. Units set to OFF mode are not included in the average. 

o If any unit within the zone is currently dehumidifying or starts dehumidifying, then all 

other units within the zone are inhibited or prevented from continuing or starting humidifi - 

cation. 

NOTE: An “EXCLUDED” message will display on the Zone Master when a unit is excluded from 

the zone by temperature or humidity calibration. 

1.2 Additional Zone Master Features: 

• Sync Slaves TSP (synchronize the units’ temperature setpoint) – With the Zone Master 

enabled, under Menu B: Setpoints, users can synchronize the temperature setpoint 

and deadband of the Master unit to all its units in the zone by selecting YES at the Sync 

Slaves TSP selection. Individual units’ setpoint can be changed at its own controller. 

• Sync Slaves Clock (synchronize the slave unit’s clock) – With Zone Master enabled, 

under Menu C: Clock/Scheduler, users can synchronize the clock of the Master to all its 

units in the zone by selecting YES at the Sync Slaves Clock. 

• Primary vs. Secondary Schedule – Users have the option to operate the Zone Master 

under a secondary schedule. The user can select the number of units to run in the secondary 

schedule and when. The scheduler in the Zone Master will take over the Setback 

Schedule in Clock/Scheduler of Menu C.

2.0 Wiring and Addressing Units within a Zone 

2.0.1 Wiring 

All communication wire must be at least 22 gauge twisted and shielded pair with a drain line. Up 

to 16 units may be connected in any order (daisy chained). Unit addresses must be assigned at 

start-up prior to wiring. 

Each unit is connected through the unit’s control module pLAN connection (J11 - See dap4 Zone 

Master wiring connection drawing for wiring details). 

2.0.2 Addressing units within a Zone 

In pLAN network, both the dap4 controller and the display have separate addresses. “Display Address” 

is the address of the display and I/O Board Address is the address of the dap4 controller. 

In a Zone Master network where all units are connected via pLAN, each unit and its display must 

have different addresses. Below is the recommendation addresses combination: 

Table 1: Recommended Addresses in Zone Master control 

Unit 1 Unit 2 Unit 3 Unit 4 Unit 5 Unit 6 Unit 7 Unit 8 

dap4 pLAN address 1 2 3 4 5 6 7 8 

Display Address 32 31 30 29 28 27 26 25 

Unit 9 Unit 10 Unit 11 Unit 12 Unit 13 Unit 14 Unit 15 Unit 16 

dap4 pLAN address 9 10 11 12 13 14 15 16 

Display Address 24 23 22 21 20 19 18 17

2.0.3 Changing the address of the dap4 controller: 

Since all units will be shipped as Unit #1, a change of Controller Addresses needs to be done in 

order to establish a Zone Master communication. 

Follow this procedure to set pLAN address to each dap4 controller in the zone: 

• Press button A for 5 seconds by using a small screw driver or a small pin. The pLAN address 

will start fl ashing. 

• Press repeatedly or hold the button until reaching the required address (2, 3, 4…16). 

Note: You can set up dap4 address from 1 - 16. Address 17 to 32 are reserved for display modules. 

Follow the table on previous page to set the display module address. 

• Wait until the address starts fl ashing rapidly. In this stage the address has been saved but it 

not yet active for the application program. Power down the controller. 

• Power up the controller again. The address is now set to the dap4
